While the manhunt is in progress

Chapter 644
While Ishikawa Hayato was observing the huge hexagon on the paper, Song He had already drawn a rough topographic map of Sandu in the hexagon.

And Hayato Ishikawa looked at the scaled down map, and found that it was indeed as Song He said, that the entire Sangdu was included in this hexagon.

"That is to say, none of the three ancient books have left the range of Sandu?" Hayato Ishikawa understood, but then doubts arose in his heart again, and he asked, "Then where are the specific locations of these three books?"

"Don't worry." Song He waved his hand to signal Hayato Ishikawa to relax: "Looking at the map, these six locations are remote, four of them are wasteland, and there is nothing worth noting, so I think going to these Local scouting doesn't make much sense."

"Since there is no meaning for investigation, the only use for them to be marked by thieves is to locate them."

"Positioning?" Ishikawa Hayato finally recovered from the shock, and guessed with his eyes turned: "Three points are determined by six points, and they are not outside the range of this hexagon, so it can only be the intersection of his internal lines. .”

"That's right, you can regain your ingenuity after you calm down." Song He smiled and said, "The intersection of the internal lines of a hexagon can only be the intersection of diagonal lines. However, there are fifteen intersections in total, one The individual investigation is too cumbersome, not to mention that it may involve some troublesome places."

"So I carefully checked the positions and angles of these surveillance cameras, and found that they are still somewhat related."

Song He said that he numbered the six vertices of the hexagon on the paper clockwise, and replaced them with numbers one to six.

"After comparison, I found that although the positions of these surveillance cameras are different, the angles and lens orientations of the images that can be captured are the same." Song He wrote quickly, and in the blink of an eye, No. [-] and No. [-], No. [-] and No. [-], and No. [-] No. and No. [-] are respectively connected.

I saw an equilateral triangle surrounded by three diagonal lines inside the hexagon, and the three vertices of the triangle are exactly the intersection points of these three diagonal lines!
"This is..." Hayato Ishikawa looked at the equilateral triangle on the paper in surprise, and quickly took out his mobile phone before finishing his sentence, and contacted the police for investigation.

Song He waited for Ishikawa Hayato to finish the call, and said with a smile: "Remember our agreement."

"Mr. Sun, please rest assured." Ishikawa Hayato was obviously in a good mood: "I promise that after the three ancient books are found, they will be sent here as soon as possible."

Song He nodded, let Ishikawa Hayato take away his hand-painted drawings, and continued to enjoy his unfinished lunch.

Two hours later, Ishikawa Hayato returned to Song He with a smile on his face, and brought with him three ancient books kept in a portable safe.

Putting on the special gloves for maintaining ancient books, Song He carefully took over the ancient books that Hayato Ishikawa also carefully handed over.

"Sure enough, it's a long time ago. I'm afraid it will break if you turn it harder." Song He frowned, flipping through the pages one by one.

"When we found these books, they were buried underground, and the safes for storing ancient books are very high-end..." Ishikawa Hayato's expression suddenly became a little tangled, and he paused before saying: "...far more advanced than museum safes , as if for long-term preservation."

Nonsense, he doesn't even know when I will come, so why not plan to keep it for a long time...

Song He Nian turned around, and asked nonchalantly, "Then why don't you just use the other party's safe?"

"Naturally, it's the ridiculous pride and dignity in mediocrity at work." Ishikawa Hayato shook his head disapprovingly, and then added: "Of course, there are also factors that the police want to investigate the thief's information."

"In short, thieves are not ordinary people."

"I don't understand, it's true for everyone." Song He pretended to sigh, and at the same time patiently turned the pages of the book gently, for fear of accidentally destroying the ancient book in his hand.

An hour later, Song He returned the three extremely fragile ancient books to Hayato Ishikawa, and he firmly remembered all the contents of the books.

But after returning the ancient book, Song He fell into confusion, because he couldn't find the third message left by the mixed-race man at all!

It shouldn't be, after these three books are lost, they must never appear on the surface again, and this kind of thing is completely inconsistent with my aesthetics, and it is clearly not something that is meant to be given to me...

For a while, various thoughts came and went in Song He's mind, and he asked tentatively: "Shi Chuan, have you found any clues related to the thief in the place where these things are hidden?"

"No." Ishikawa Hayato replied: "The three safes are either buried in the soil or placed on the roof. There are no traces of value at all. The possibility of catching the thief is basically zero."

"That's it, that's quite a pity." Song He Wenyan stood up, stretched his waist and said, "Since the matter has been resolved, I will leave first. Remember to keep it secret for me, Xin Jinghai is only returning to China for a short rest. After a while, I’m going to go abroad again to make a living.”

Ishikawa Hayato smiled and said: "Mr. Sun, please rest assured that your real identity is a secret among secrets. There is no record in the text files. Only my family and I know."

"Reliable!" Song He laughed, chatted with Ishikawa Hayato for a while, and left after being persuaded by the other party's enthusiasm. After going out, he went around and changed his outfit, and changed into the appearance of gambling in Aocheng, leisurely and leisurely walking on the street.

According to the information in his memory, Song He came to the nearest location where ancient books were buried, and turned around in a circle as if by accident.

However, Song He still found nothing this time, and just when he was wondering what the information left behind by the mixed-race man was, the entrance of a subway station suddenly appeared not far away, and the several numbers marked on the entrance sign instantly attracted Song He. What attention!
I'll go, if I don't come here, I will be called a ghost if I can find out...

While complaining secretly, the ciphertext logic of the mixed-race man flashed across Song He's mind, and he directly translated the numbers!

"of"?I was really lucky, the first thing I found was such a word...

Having found out, Song He quickly inquired about the subway station entrances of the other two book collection locations, and got two other hidden pieces of information, namely "Unique" and "Point".

After complaining about the mixed-race man again, Song He went straight to the center of the equilateral triangle formed by the three book collection points according to the picture in his memory.

Finally, when Song He came to the location indicated by the message left by the mixed-race man, he couldn't help but sighed with a wry smile: "Brother, you're never finished!"

I saw a residential building with more than 21 floors standing at the location indicated by the mixed-race man, and on a window on the [-]st floor, there was a huge fireworks show poster.

With a sigh, Song He calculated the room where the window belonged and walked into the apartment building very naturally.

Arriving at the 21st floor, Song He observed for a while, then took out the key from under the floor mat at the door of the target room, listened carefully, and then calmly opened the door and entered.

This is a room that has been simply decorated, and a monitor facing the door is installed in the corner, and the working indicator light is blinking, obviously transmitting the situation in the house in real time, but it is not known where the receiving end is.

Song He looked like he was in Aocheng at this time, and he was not afraid of being photographed. He smiled and waved at the camera, and then his eyes fell on the two suitcases in the house, one big and one small.

After approaching the suitcase, Song He found that it was not locked, so he opened the smaller one casually.

I saw a mask with unique workmanship inside. The material is light and breathable, and the lines are delicate and exquisite, but the facial makeup drawn on it exudes a sly temperament.

Song He looked at the mask, which was obviously newly made, with a satisfied smile on his face, put it on gently, and then opened the large suitcase beside him.
